 Abstract 

This paper presents an enhanced Phase-Locked Loop (PLL) method using the Goertzel algorithm to improve the performance of Power Factor Correction (PFC) and LLC resonant converters. By eliminating the current sensor at the DC-link capacitor and allowing the LLC converter to operate within the PFC converter's frequency range, the new method ensures efficient Zero Current Switching (ZCS). Experimental and simulation results demonstrate that our approach significantly improves the power factor compared to conventional methods. This solution simplifies the circuit design, reduces overall costs, and increases system reliability.

Signals and Circuits – Baskakov-

 

About the book 

The present book is a course on signals and circuits as it is taught in the USSR. This subject figures prominently among the fundamental disciplines essential to the expertise of communication engineers. Keeping pace with overall progress in science and technology and reflecting the current trends in component design and theory, this course combines and sets forth in a systematic way the most important principles in the field of communications. In his work on the text, the author has been guided by the idea that material should be specifically tailored to the teaching practice at college. This approach has governed the selection of material and the degree of detail in its presentation: its pages contain what, as the author believes, the student can fully assimilate during the time allotted. Specific circuit types, their study and comparative analysis-all this belongs to the specialized subjects in communication engineering. This text includes a wide variety of material and a wealth of concepts and techniques which will come the student’s way for the first time. Ample space is devoted to mathematical tools of study. To link theory closer to practice, the chapters contain a great number of examples and problems giving the student deeper insight into the techniques of engineering analysis. The book was translated from Russian by V. Kuznetsov was published in 1986 by Mir Publishers
